SPECIFICATION forming part of Letters Patent No. 542,287, dated' July 9, 1895.

Y Application filed November 15,1894. Serial No. 528,871. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, WALTER J. SMART, of'

Brooklyn,in'the county of Kings and State of New York, have invented a certain new and useful Improvement in Lamps, ofwhich the following is a specification. 2

My improvement relates particularly to lamps of the regenerative type.

I will describe a lamp embodying my improvement and then point out the novelfeatures in the claims.

In the accompanying drawings, Figure lis a transverse section of alamp embodying my improvement. Fig. 2 is a central vertical section of a portion of the lamp, and Fig. 3 shows a modification in the form of the burner-body and deiiector.

Referring by letter to the drawings, A designates a gas-supply pipe, which may lead from any desired source. I have shown but one supply-pipe A as communicating with the burner-body B; but it is to be understood that a similar pipe communicates with the l opposite end of the burner-body. They of course may communicate with a single main supply-pipe.

The body B of the burner is shown of straight tubular form, and at its ends engages with couplings a, with which the pipes A also communicate. The outer ends of the coup` lings are provided with removable plugs a', which facilitate the cleaning of the parts.

Cdesignatesacasting comprising end pieces c and arc-shaped pieces or diaphragms c c2, extending between the end pieces above the burner-body B. rl`he end pieces c andl the arc-shaped pieces or diaphragms form a tube above the burner-body B, which forms a part of a iiue, through which the waste products of combustion ascend. A line C', of sheet metal, may extend from the upper portion thereof, as indicated.

To provide a combustion-chamber aroundthe burner-body, I employ, in conjunction With the casting C, a transparent or translucent material D, which is transversely curved around the lower portion of the burner-body and has its edges engaged with the'portions c c2 of the casting G and has its ends engaged with the circular end pieces c of the casting. 1

In this improvement I have provided two sets or duplicate sets ofjet-tubes. These consist of small tubes B B2, extended at opposite angles from the burner-.body B.

I have indicated by dotted line ct in Fig. 1 and full line in Fig. 3 a partition B3, extended transversely through the burner-body to divide it into two parts, or, in other words, to form it into two burner-bodies, and the jet-tubes communicate with the respective burner-bodies.

D2 indicates a defiector-plate, which in Figs. l and 2 is shown as formed in the arc of a circle and as extending over the burner-body or burner-bodies. The ends of the plate are secured to the end pieces cof the casting Gand the lower edges are substantially on a horizontal plane with the outlets of the jet-tubes. Air is admitted between the, plate D2 and burner-body through an opening d in an end wall of the casting.

In lieu of the single deiiector-plate D2, I may employ two plates transversely curved, fastened one on each side of the burner-body, as shown at D in Fig. 3. In either case air is admitted through the opening d D3 is a substantially trough-shaped plate extended beneath and parallel with the burnerbody. It is open at its top, and its side and bottom Walls are perforated. The side walls extend upwardly nearly to the jet-tubes, and air is admitted to the interior of the plate D2 through an opening d in the end wall of the casting C. The ends of the plate D2 are secured rigidly to the end portions of the casting.

In operation, air admitted through the opening d will become slightly heated and heat the gas-supply, and air to support combustion will enter through the opening d and pass in small jets through the perforations in the plate D2 and directthe flame around the detlector-plate.

' Having described my invention, what I claim isl. The combination with a combustion chamber, of a burner body extended lengthwise in said chamber, two series of jet tubes extended therefrom and a defiector plate having its lower edge substantially on a horizontal plane with the jet outlets, substantially as specified.

2. The combination with a combustion chamber, of a burner body extended length- ICQ wise therein, two series of jettubes extended at opposite anglesfrom the burner body, a deiiector plate extended around a portion of the burner body and a trough sbaped'plate, having perforated walls, beneath the burner body, substantially as specified.

3. The combination of a combustion charnber, a. straight burner body therein divided into compartments by a partition, a set of jet io tubes extended from each of said compart ments, the deiiector plate and the perforated WALTER J. SMART. Witnesses:
